Make SURE you downloaded the right ROM for P765. If you sure that is the right ROM, open the ROM zip with 7zip and go to META-INF/com/google/android/ and extract updater-script. Open it with Notepad++ (only Notepad++, not Notepad/Wordpad), and delete the first assert() command, like this:

Yup like the last two guys said you get status 7 when you try to install KitKat with an outdated recovery. Update your recovery and you can reflash the cm11.

I have a LG P769 just as you, but I cannot seem to find a newer CWM recovery to install than the one I already have, namely L9RecoveryInstaller_1.5.0.apk which contains clockworkmod version 6.0.1.2. With this verson, I get the same (Status 7) error as everyone else.

So my question is, could you please point me to exactly the (CWM?) recovery mode you are using, and instructions for how to install it given that I am already using an older version of CWM?
